Everyone has a favorite side of the bed they sleep on, and according to psychologist Hope Bastine, who also happens to specialize in sleep analysis, the side of the bed you prefer can reveal different things about your personality. Apparently, people who prefer to sleep on the left side of the bed are generally more cheerful than their right-side counterparts. They also tend to be able to handle stress better and are more confident overall. While not quite as cheerful as lefties, right-side-of-the-bedders are more grounded, realistic, and prepared for worst-case scenarios and crises. (Cosmo)
